WILLIAM G. PERKINS, OF SANDY POINT, MAINE.

WRENCH.

SPECIFICATION forming part of Letters Patent No.384,467, dated June 12,1888.

Application filed March 20, 1888. Serial No. 267,886.

To all whom it may concern.-

Be it known thatl, WILLIAM G. PERKINS, a citizen of the United States,residing at Sandy Point, in the county of Waldo and State of Maine, haveinvented certain new and useful Improvements in Wheel-Wrenches for Axle-Nuts; and I do declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings,and to letters or figuresofreference markedthereon, which form a part ofthis specification.

Figure 1 of the drawings is arepresentation of the invention, shown :insection attached to the wheel. Fig. 2 is a front view, and Fig. 3 is aside view.

The invention relates to improvements in vehicle-wheel-nut wrenches; andit consists in the construction and novel combination of parts, ashereinafter set forth.

The object of my invention is to provide a simple wrench that may besecured to the nut and hub-band by one operation, so that the nut may betaken off and replaced with the wheel by turning the wheel in the properdirection.

Referring to the drawings, A designates a wheel-hub; B, the bandthereon; O, the threaded axlespindle, and D the nut.

E represents the two parallel jaws of the wrench, one of which hasthetenon ends a pivoted within the rectangular collar (1, and the other isrigidly secured to said collar. Both jaws are provided near theiropposite ends with the outstanding bearing-lugs b. The jaws E in theends opposite the pivotal point have the angular nut-seat b, adapted toengage the four sides of the nut D.

F shows levers fulcrumed on the pivot 0 between the lugs b, and havingthe outwardlyopening ends 0, for engaging the inner surface of thehub-band, as shown. The levers are longitudinally slotted, as at (Z, andthe jaws E (N0 model.)

have the transverse openings d in line with said slots. A threaded bolt,G, passes through the slots (1 and openings (1, and to prevent it fromturning the portion 6 adjacent to the head may be squared, as shown. Anut, H, provided with a crank-handle, c, engages the threaded end of thebolt. As the nut H is turned down on the bolt, the levers are forceddown,bringing the ends 0 against the innersurface of the hub-Band, andthe pressure on the band clamps the angular jaws on the axle-nut; thenby turning the wheel on the spindle in a direction opposite to thedirection of the spindle-thread the nut is disengaged and the wheel andnut may be taken off together. After the axle-skein shall have beenoiled or greased, the wheel and nut may be replaced and the wrenchremoved by loosening the. nut on the bolt.

Springs I are provided to throw the lovers outward.

Flat springs, as shown in the drawings, may be used; or, if preferred,spiral springs may be substituted.

Having described my invent ion,whatl claim 1s 1. A wheel-nut wrenchconsisting of thejaw pivoted within the rectangular collar, the fixedjaw, the respective jaws being provided in their ends with the nut-seat,the outstanding bearing-lugs, the levers fulcrumed between said lugs,the threaded bolt, the nut, and the springs, substantially as specified.

2. The combination, with jaws E, of the levers fulcrumed thereon, thethreaded bolt passing through the slots in the levers and the openingsin thejaws, and the nut having the crank-handle, substantially asspecified.

In testimony whereof I affix my signature in
